FPGA-based digital quadrature down-converter design, ALTERA the DE2 development board to design a polyphase filter structure of the digital quadrature converter. Polyphase filter module which is the most critical module, 64-order filter coefficients are divided into two parity, and stored by VHDL constants inside the module. These constants are called by MATLAB FDATool, according to filter parameters required to generate the. These floating-point format in MATLAB filter coefficients need to be calculated into a binary form of complement, it can be stored in the module.
